L7 15 not sounding right.how do I wire the sub in a ported box


It's quite simple, positive from amp to positive of speaker, negative to negative. Make sure it's getting sub frequencies only and not full spectrum signal. Next (if everything checks out so far) see if the box dimensions and ports are correct for your sub. The sub and box combo will have lots of factors when considering tuning of the box and port size. You can find all sorts of info on the website for your sub. Qtas, max excursion etc etc etc. They might even list a few total volume and port dimension sizes for the sub you have and your taste in music. It's quite a science to get it right. More than buying a sub and buying/building a box to get great performance. When you get it right though... music to your ears (and chest)

Hi i have a 15"w3-d4 jl audio sub,can anyone tell me what size antype box i should use ie sealed or ported and the box dimensions


Hi,
I've had a look at the JLaudio website and they recommend 2 box designs, a ported and a sealed.
The sealed box needs a volume of:
2.125 ft3 or 60.2 litres.
To get this you would need to build the box to these dimensions:
22" x 16" x 14.75" or 559mm x 406mm x 375mm
The ported box needs a volume of:
3.50 ft3 or 99.1 litres.
To get this you would need to build the box to these dimensions:
24" x 19" x 18" or 610mm x 483mm x 457mm.
The port needs to be:
3.0" x 10.9" or 76mm x 277mm.
The enclosure recommendations listed above are external dimensions which assume the use of 3/4" (19mm) thick material. If you are using 5/8" (16mm) thick material, subtract 1/4" (6.5mm) from each dimension. Do not use any material with a thickness of less than 5/8" (16mm) as this may compromise the rigidity of the enclosure.
• All enclosure volumes listed above are net internal volumes! Driver displacement, port displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into acount.
• When using two subwoofers in a common enclosure simply double the required volume and, in the case of a ported enclosure, use two times the recommended port(s). Likewise, when using three subwoofers in a common enclosure simply triple the required volume and, in the case of a ported enclosure, use three times the recommended port(s).
• We recommend the use of this speaker in a bi-amplified system using high-quality satellite speakers and a high-quality amplifier. We do not recommend the use of this subwoofer with a passive crossover (coil), as this type of device will adversely affect performance.
As you can see it all depends on the space you have available, whilst the vented box will give you a more efficient bass responce especially with the low range frequencies.

If you to go and look at the information about your sub woofer and find out all the information about building or buying the correct enclosure then this is the link to the pdf file I found:
The enclosure info is on page 3:

I am building a custom box for 2 15 inch Kicker L7's. These will go in the trunk of an 04 Impala. Do I need 4 or 5 cubic feet per chamber in a ported box? Also, what size port should I use? and how long? I...


Hello bgl6176,

According to their specs, the L7's will work in a ported enclosure with as little as 3 CuFt and up to 6 CuFt. Usually with ported, bigger is better, so let's use the 5 CuFt per chamber. I'm assuming that you have room for a 10 CuFt box in the trunk? That's a big box? Almost half as big as a medium sized refrigerator. I hope you don't plan on putting your golf bags in there too. For 10.15 CuFt, a box will need to be 36X29X20, allowing 0.15 for the partition, sub, and port displacement.

To tune each chamber to 30Hz, you need a 4" diameter port 4.6" in length. Lots of custom builders use PVC and even ABS pipe for round ports. You can also buy "pretuned" ports from sites like www.partsexpress.com.

You'll have to measure the exact room that you have available and then adjust the dimensions accordingly.

Here's a link to a great site for calculating almost anything in box building and subwoofer related. You can use the old "multiply LxWxD and divide by 1728" and the other formulas too, but here you can plug the figures in and immediately see the results.

Building a box, need to know best dimensions for box and port


Hello dirt_digger6,

The specific sub you are asking about would seem to be the TS-302F which is the only 12" 800W Pioneer I have located.

Directly from Pioneer's support knowledgebase:
TS-W302F = Ported: 2.5 Cu.Ft. F3 = 39HzPort: 4  x 6.5 tuned @ 37 Hz with 12 % port noise.

An enclosure 16X18X21, constructed from 3/4" MDF will yield 2.69 Cu.Ft., allowing .19 Cu.Ft. displacement for the sub and port.
There's an excellent "box calculator" located here on the12v.com web site. You can measure the space you have to put the box and fiddle with the dimensions to get close to your ideal volume. There are also calculators on the12v.com which will allow you to calculate a port length based on port diameter (or width/height), enclosure volume, and desired tuning frequency.

Hope this helps.

Box dimensions for 15 in cerwin vega


do you want the box ported or unported (holes or no holes) if you don't got a lot of room than you dont want a ported box. keep in mind the box has to have the correct amount of cubic air space or you could seize your sub... if you're building it make sure you use OSB board (oriented strand board) or MDF board(medium density fiber) your sub needs .7cubic feet of air space in an unported box

Dimension please for enclosure 12w3v2-d2


Typically you use one cubic foot per sub, so a 2 cubic foot box will work fine. To build a basic one, just a rectangular box, using 3/4" MDF (excellent material for a box), cut pieces this way:

2 - 25.5" x 13.5"
2 - 25.5" x 12"
2 - 12" x 12"

This will give you an interior volume of exactly 2 cubic feet. Cut your sub holes out of one of the 25.5" x 13.5" pieces.

Enclosure type


Sealed box and somewhat large if they are 12's I usually try to get 3 cubic feet overall internal dimensions and generally the inside dimensions will be 13" tall 32" wide and 13"-14" inches deep. with no divider and make sure the box is sealed. Personally I like to phase the speakers backwards. Gives the bass a little more rumble.
